foley would somehow alter u.s. policy, the president made clear, no change in the u.s. posture right now toward them. if anything, a strengthening of the u.s. posture towards them. >> absolutely, and that's what analysts have been saying as well. that's really the u.s.' one choice here given what we saw on that video, and that sends a message to the world as well of the brutality of this organization. i think we saw the president use remarkably strong words. laying out, you know, kind of based on what we've done, what we will continue to do, saying we will be vigilant and we will be relentless. we must extract this cancer so that it will not spread and that we will continue to confront this hateful terror, he said, and replace it with hope. so obviously the u.s. involvement and the way we have been involved will continue. i thought it was interesting, too, to say, you know, this is the u.s.' stance and that's going to continue as strong, if not stronger, than it has been over the last week or so.
